Does anemia (a decrease in the number of red blood cells) increase or decrease blood viscosity?

Match each description to its corresponding blood component.

Indicate which letter in the diagram is pulled towards the middle of the sarcomere during muscle contraction.

Indicate which letter in the diagram propagates the action potential to the middle of the muscle fiber in order that all myofibrils be recruited in the generation of tension/force.

Identify the labelled structures on the muscle model.

In a resting muscle, the myosin binding sites on the actin are blocked by:

What allows the myosin heads to unbind from the actin filament?

Muscle contraction (power stroke) within the sarcomere involves:

Place in chronological order the statements describing muscle contraction.
